My first post.
Working on a ZD331 (2008)
Downloaded the service manual last week.
Shut it down for a blade change, let it down, all systems down.
Have gone through and cleaned all the safety switch connections, and verified operation.
LH/RH controls in out/neutral -normal open.
PTO disengaged -normal open
Seat -normal open
Brake locked -normal closed.
Cleaned and checked harness connectors as well as relays and control module.
Replaced solid state relays and control module.
Cleaned and checked key switch continuity - good.
Key in on position fuel stop solenoid operates as well as fuel pump. Can jumper hot to white on starter and start the thing and shut it down with the key.
Moving through preheat to start, no juice to starter relay circuit.
Fuse block good, red wire hot at the switch, red yellow hot at ON, no power on pink at PREHEAT, no GLOW bulb on, No FUEL bulb on. Have OIL and CHARGE bulbs on.
And it just gets worse, I just lost everything.
